MATRIX MATERIALS FOR THE CONDITIONING ORGANIC RADIOACTIVE WASTES

There are a variety of matrix materials and commercially techniques available for conditioning organic radioactive wastes. This paper provides an overview of the application context and evolution of several important matrix materials and offers comments on the waste form requirements under disposal conditions. In this paper emphasis has been placed on the conditioning options available commercially and that have, to various degrees, been demonstrated to be viable. At the same time, it is recognized that other matrices are being researched as possible for future options. Included in these options are magnesium phosphates binding systems and mixed cement with Portland composite cement and Calcium Aluminate Cement.
